The $221,000,000 apartment was purchased by Ukrainian billionaire Rinat Akhmetov. Many newspapers and media sources had been scrambling to discover the discrete mystery buyer who had conducted the deal through proxy; however, the Financial Times was first to discover the identity of the buyer. Details of the apartment, as reported by The Guardian, Forbes and Gawker, are that the penthouse apartment was created by joining two five-bedroom 12,500 square-foot units into a 25,000 square-foot apartment complete with a wine cellar.

The unit was sold as a shell with the buyer reportedly contracting design- and development-firm Candy & Candy to complete the interior for $97,000,000.

One Hyde Park, designed by Rogers Stirk Harbour + Partners and engineered by Ove Arup & Partners, is a collaboration between Hamad bin Jassim bin Jaber Al Thani and Candy + Candy through the company Project Grande Limited. The 86-unit project features a bronze-and-bulletproof glass facade offering a total of 370,700 square-feet of residential space and 9,000 square-feet of retail. It was built for a mere £500,000,000 [$812,650,000] with current prices selling for nearly $9,500 a square foot.

Despite all of this, Candy + Candy just posted a loss of £890,000 [$1,446,517] reducing its number of staff by 17 according to Building.co.uk.
